New Opera update makes Tradingview charts very slow

A Former User @avl

Hi @avl, I have uploaded a video to demonstrate the difference between Vivaldi & Opera as it is now.

I'm not sure how clearly the lag comes across in the video, but it's pronounced when using it.

Cheers.

Hi, can you post the details found on opera://gpu on your system somewhere?

Even better if you could also post vivaldi://gpu from Vivaldi (or install an older version of Opera that worked correctly and post those contents) so we can check if anything changed.

the problem happens in the new updates of Chrome and Opera. It does not happen in Firefox or Vivaldi.

Opera, like Chrome, is based on Chromium, so it makes sense that an issue found there propagates to Opera. Vivaldi is also based on Chromium, but is currently using an older version, so they don't have the issue yet. Firefox is not based on Chromium.

@avl, here is the opera gpu which you can view online

and the vivaldi

I can try to get an older version of Opera tonight or tomorrow night. Cheers

Hi @avl,

As requested I downloaded an older version of Opera (ver. 51 - see the link for the screenshot) and it worked perfectly – very fast. So clearly something in update of 52 has screwed it up. The gpu for it is the second link

Looking at Opera 51 and Vivaldi compared to Opera 52, in the new update Canvas and Rasterization are not accelerated, whereas they were accelerated in 51 and Vivaldi. Could this be the problem?

@ezodi Most probably. Is Vivaldi based on same Chromium version of Opera 52?

A Former User @leocg

@leocg, no, @avl said that Vivaldi is using an old version of Chromium. I just wonder if there's a way to manually turn on the acceleration.

@ezodi It's enabled in settings?

A Former User @leocg

@leocg Can you accelerate Canvas and Rasterization in the settings? I didn't see an option.

I'm not 100% sure that that's the problem, but it's turned off in the new Opera & Chrome updates, and they are the ones causing the issue.

@ezodi I was asking about hardware acceleration in general.

You should be able force hardware acceleration for Rasterization and Canvas in opera://flags.

They were turned off most probably because of what i said in your dump of opera://gpu.

A Former User @leocg

@leocg - I turned on GPU rasterization in flags and it completely wiped out the graphics in the browser - everything was just a splash of colour. Somehow I was still able to search in flags to set it back to default. That was weird.

Turning on Experimental canvas did nothing.

I don't see any other relevant options for Canvas & Rasterization.

@ezodi The flag for Canvas would be opera://flags/#disable-accelerated-2d-canvas. However I guess you will need to wait for the problems mentioned on opera://gpu to be fixed.

A Former User @leocg

@leocg - Thanks. It says #disable-accelerated-2d-canvas underneath 'Accelerated 2D Canvas', but the option on the right of it is 'Enabled' already. So I don't know what that means, it sounds like a contradiction but I have no idea about this stuff.

@ezodi And setting it to disabled made no difference?

A Former User @leocg

@leocg - No, it didn't work.

and this isn't just a problem with Tradingview. You can see and feel it on the Bitcoin charts at bitcoinwisdom.com – they never lagged like this before the update in Opera & Chrome

@ezodi So I guess you need to wait for the issue to be fixed by Chromium and/or Intel and/or Apple.

A Former User @leocg

@leocg - Thanks for trying mate.

Hi @ezodi, what happened is that Chromium put your combination of GPU (Intel) and OS (macOS 10.11?) on a blacklist because it was causing rendering corruption issues. You can read more details about that issue on https://bugs.chromium.org/p/chromium/issues/detail?id=794819. To fix the rendering corruption, they have disabled acceleration of canvas / rasterization.

I recommend you keep all your settings on default, there's really not much to do here. The only real way to fix it is to update macOS to 10.12 or higher (the bug in the GPU driver that causes the rendering corruption was seen only in macOS 10.10 and 10.11, which is why they only disabled acceleration on those systems).

Hi @avl – first of all thank you very much for all the work you've put in to figure this out. I'm grateful for your help.

Maybe it's superstition, but I had noticed my 2013 Macbook Air was slowing down a bit and I didn't want to upgrade to Sierra in case it exacerbated that. I've done it now though – 10.13.4 – and like you said it's fixed the problems with Tradingview, both for Opera and Chrome. It's fast and smooth again, more so in Opera than Chrome I think.

I find it a bit strange that the acceleration was disabled when I never experienced a problem with anything until the new upgrade, but that's all done now. Opera's great and I'll continue to use it as my main browser.

Thanks again for all your help. Cheers.
